Application led May 6,

To all whom t may concern:

Be it known that l, SOLOMON Wisin, a citizen of the United States, and aresident of the city of Cincinnati, in the county of Hamilton and Stateof Ohio, have invented certain new and useful Improvements in Locks, ofwhich the following is a Jfull, clear, and exact description, referencebeing had to the accompanying drawings, forming a part of thisspecilication.

My invention relates to key operated locks, having tumblers, and moreparticularly to that type of locks wherein one set of tumblers isbrought into line by another set, or by a suitable key, thereby forminga line of cleavage for the opening of the locked members that carry saidtumblers.

lt has as its object the provision of a lock which is operated by adouble set of concentric plungers and by such means to provide a lock ofgreat strength and safety and at the same time, one which is simple tomanufacture and assemble, and hence quite inexpensive.

My objects and other advantages to be noted ll accomplish bythat certainconstruction and arrangement of parts to be hereinafter morespecifically pointed out and claimed.

In the drawings, y

Figure 1 is a sectional view taken centrally through a padlockillustrating my invention and vshowingthe lock closed..

Fig. 2 is a like view of Fig. 1 showing the lock after it has beenreleased.

Fig. 3 is a perspective view of the various springs as employed inconnection with the lock shown in Figs. 1 and 2.

Fig. 6 is a cross section of the said other form of lock, showing samein closed position.

Fig. 7 is a like view to lock released.

The two` locks shown in the drawings have been selected by me as simplemeans of illustrating the principle involved in my invention, and not atall as indicating any limitations in the application of my invention tolocks in general,

Patented' Sept. 6, 1Q21.

1920. Serial No. 379,386.

The lock shown in Figs. 1 and 2 comprises a body portion 1 having acylindrical openmg 2 for the operating plungers or tubes, and a socket 3for the shackle, this lock bemg a padlock. The cylindrical opening opensinwardly of the body, toward an opening l 1n which slides the block 5.The block 5 carries the swiveled shackle 6, which when the block is inlocked position will be engaged in the socket 3, and when the block ismoved along in the opening` Al, will be free of the socket, so as topermit removal of the padlock from whatever device is in engagementtherewith.

'llhere will be a casing around the lock, as at 7 inclosing the slidewayfor the block, and the cylindrical hole in the lock body will terminateoutwardlyin a slot 8, through which the key will be inserted. The blockhas a cylindrical passage-way 9 therein for a series of tubularplungers, as in the case of the body, the parts being so arranged thatthe tubular plungers in the block will be projected into the cylindricalbore in the body, when the padlock is closed.

The tubular concentric plunger-s which form the basis of my invention,independent of the'i'orm of mechanism in which they are used, are shownin both illustrations as being four in number. Thus the locking plungersarev shown at 10, 11, 12 and 13, said plungers being mounted one insideoi the other, so as to form, preferably, a snug sliding fit. The innerplunger need not be tubular, as it forms the core of the plungerassembly. v

With each set of Vlocking plungers, there are furnished a set ofsprings, likewise concentric, as shown at 10a, 11, 12a andk 13, runningfrom a wide to a narrow diameter.

As is evident the absolute iit into each other of the tubes orconcentric plungers is not necessary, and the assembly of them into thelock is very sim-ple. They are merely set together the one inside of theothers and the springs likewise assembled. The springs are then droppedinto the socket oi the movable portion of the lock, and the plungerassembly dropped in after them. K'

The releasing or alining plungers are like the locking plungersconcentrically mounted, and except for the inner one are of tubularform, as shown at 14, 15, 16 and 17, these plungers fit snugly andslidably, although the exact dimension is not essential, and correspondin size to the locking plungers. They are easily assembled and aremerely dropped in place in the bore of the body of the lock.

The result of the structure now described is that when the blockcarrying the locking plungers is moved to a position which permits itsspring pressed plungers to move into the bore of the body of the lock,they will at once be projected therein, and prevent further movement ofthe block, until they each one move out of engagement with the saidbore.

To accomplish this unlocking movement, a key is provided having steps14a, 15a, 16a and 17a, said steps being formed by preference at eachside of the axis of the key, as Shown. There is also another stoppingstep 18a to limit the inward motion of the key.

The key when inserted in the slot 8 will contact with the four plungers14, 15, 16 and 17 and press them inwardly, andthe plungers of the twoseries are so proportioned as to length, that when the key has beenpressed home in the slot, the releasing plungers will have depressed thelocking plungers, so that they are all pressed out from the bore of thebody of the lock, and a line of cleavage formed between theltwo sets ofplungers at the meeting line of the block and its slideway.

Nothing has been stated as to the definite length of the plungers of thetwo series, since this may be as desired. I prefer, however, that theybe of varying relative sizes, dependent upon the nature of the key thatis to be employed.

As is evident the variety of locks may be extremely wide, whenv formedaccording to the concentric plunger principle which 1 have abovedescribed, since the length of each plunger may be varied fractionalparts of an inch, and each change of any plunger will vary the operationof the lock and require a different key. Thus in a lock of the characterdescribed having eight plungers in all, there Vmay be a variation,within quite wide limits of any one of the eight, which will demand adifferent shape of key and comprise a different lock which will openwith no other key.

As another form of Vlock embodying the concentric plunger device, I haveshown a Vrevolving lock structure (Figs. 5, 6 and 7). In thisvstructurethe core 18 of the lock is held stationary in the casing 19, as is theplate 20, which in connection with the casing formsthe retaining socketAfor the locking bar.`

The revolving piece 21 carries a locking bar `or finger 22 and revolvesaround the central core, inside of the casing. The piece 21 has acylindrical hole therein which carkey is to be rocked, to swing therevolving Y piece and its finger 22 into unlocking position. 1

As heretofore stated, the above two embodiments of my invention areillustrative,

and I do notvdesire thatmy claims that follow be limited in constructionbecause of my failure to describe other structures likewise illustratingthe principle of my invention. Having thuadescribed ymy invention, what1 claim as new and desire to secure by Letters Patent, is
